　擠壓成型散熱器一般為高功率散熱元件和散熱系統(tǒng)，文軒熱能根據(jù)現(xiàn)有成熟的鋁擠型型材散熱器技術(shù)，可以提供可靠的自然對(duì)流環(huán)境解決方案。通過(guò)模具實(shí)現(xiàn)鋁擠壓成型，可實(shí)現(xiàn)復(fù)雜的散熱齒片結(jié)構(gòu)。這些復(fù)雜的散熱齒片更大提高了散熱表面面積，同時(shí)降低了鋁塊加工的成本和時(shí)間。
為什么要使用文軒熱能擠壓散熱器？
（1）比沖壓成型的散熱片更高效；（2）比機(jī)械加工更節(jié)約成本；（3）有多種標(biāo)準(zhǔn)形狀和尺寸可供選擇；（4）輕松的定制實(shí)現(xiàn)比銅更輕，優(yōu)勢(shì)明顯；（5）MAX CLIP扣件系統(tǒng)無(wú)需安裝硬件和工具。

Tooth features

Fin profile #1: The fin tip has the same thickness as the fin base. The aspect ratio is smaller than 10 and this structure is suitable for cooling by natural convection.

Fin profile #2: Smaller fin tip with a larger fin base and it forms a taper. High aspect ratio which is suitable for forced air cooling products. It is more lightweight under the premise of no performance reduction.

Fin profile #3: Smaller fin tip with a larger fin base and it forms a taper. Knurls are added to the fin surface. Both fin profiles #1 & #2 are suitable for this type of design to increase the surface area. The size of the knurls is inversely proportional to the aspect ratio.
